Exaction is a term used to describe the act of demanding payment or other forms of compensation through coercion. It can take many forms, including EXTORTION, BLACKMAIL, tolls, and fees. EXTORTION is the practice of obtaining something, usually money, through force or threats. BLACKMAIL is similar to EXTORTION, but involves the threat of revealing damaging information about someone in order to obtain something. Tolls are fees charged for the use of a road or bridge, while fees are payments made for services rendered.
